A mixed interpolation-regression method for function approximation on certain planar domains
Ruymán Cruz-Barroso, Lidia Fernández, Francisco Marcellán +1
In this contribution, we introduce a mixed interpolation-regression operator for functions defined on certain planar domains. We focus on an ellipse, an annulus and a polygon. An u…

A mixed interpolation-regression method for numerical integration on the unit circle using zeros of para-orthogonal polynomials
Ruymán Cruz-Barroso, Lidia Fernández, Francisco Marcellán
A new alternative numerical procedure to the Szegő quadrature formulas for the estimation of integrals with respect to a positive Borel measure supported on the unit circle is…
